genus in my Guide, and shall do so here. The larvae of 

 Ophiusa, like those of Catocala, have 16 feet; but I suppose 

 they are half loopers, as Hiibner places them amongst his 

 ISemigeometrae. 



All the species, except the first, are very rare in England ; 

 and several of them probably are not native insects : they oc- 

 casionally fly by day. 



1. O. lusoria Lmn. S. N.83^. l^.—Curt. Brit. Ent. p/. 475. J. 

 I have taken it in a meadow at Eccles, in Suffolk, as early 



as the 10th of July ; but it is generally found about the middle 

 of August, in moist woods, Yorkshire. I have observed it at 

 Coombe, Birch, and Darent Woods. The caterpillar feeds 

 upon the Astragalus glycyphyllos (pi. 208.), and is copied from 

 Hiibner. 



2. ludicra Hiib. 65. 3l9.—Goda,pl. 56. 2. 



This and the next species are in Mr. Swainson's Cabinet. 



3. crassiuscula Haw. Lep. Brit. 259. 13. 

 Very rare in the North of England. 



4. grandirena Haio. 264. 27. 



A North American insect, a specimen of which was reported 

 to have been caught at Bristol, and is in the British Museum. 



8. scopulepes Haw. 260. 14. — inops Ste. 



I included this with the Acosmetiae, but it seems to be more 

 allied to Ophiusa. - 



Specimens are in Mr. Haworth's Cabinet and the British 

 Museum, from the Duchess of Portland's Collection. 



Gen. 882^. Catephia Och.^ Treit. — Ophiusa Curt. 

 " Wings, superior dark coloured, with sombre markings : 

 inferior at the base, light coloured, with a broad dark margin. 

 Antenna; setaceous, slightly pectinated. Abdomen dark co- 

 loured, with tufts of hairs on the posterior segments*." 



5. Alchymista Hiib. 62. 303. — Goda, pi. 5'i.f. 1. — leucomelas 



Linn. ? — convergens Fab. 



Formerly in the Collections of the Duchess of Pordand and 

 Mr. Haworth. 



The caterpillar feeds on the Oak and Elm, and is found in 

 forests in France ; the moth appears in June. 



6. O. trifasciata Ste. 



Reported to have been taken by the Rev. W. Kirby at 

 Barham. 



The Plant is Bupleurum rotundifolium (Common Thorough- 

 wax), communicated by the Rev. Dr. Jermyn.
